Stainless Steel External Threaded Hollow Multi-Step Connector

Product Overview

This product is a stainless steel hollow multi-step connector with an external thread, machined from one piece of high-quality stainless steel with a bright brushed silver finish for excellent corrosion resistance and a clean appearance. It features a disc head with a hollow port at one end, a precision external-threaded body in the middle, and a multi-step structure at the other end, with a through hole running along the central axis. The threaded end screws securely into standard threaded holes, the through hole allows liquid or gas media to pass through, and the multi-step end is designed for mating with hoses or fittings. It is a practical and reliable threaded connection and transition component for machinery and piping systems.

 

Product Features

High-quality stainless steel: Made of high-quality stainless steel with excellent rust and corrosion resistance, the bright brushed silver surface is durable and suitable for a variety of working environments.

Precision external thread: The external threads are clearly formed, uniform and complete, providing smooth engagement and firm meshing with standard threaded holes for a strong and reliable connection.

Hollow through-hole design: The axial through hole allows liquid or gas media to pass through, combining media transfer with connection in one component.

Multi-step structure: The multi-step end fits hoses or fittings of different inner diameters, enlarging the contact area for a more secure and reliable connection.

One-piece machined construction: The disc head, threaded body and multi-step structure are machined from one piece with no welded weak points, providing high overall strength and a long service life.

 

Application Field

This product is widely used in machinery, hydraulic and pneumatic systems, automotive and engineering equipment, water treatment and general piping as a transition connector for threaded connection and media transfer. It is especially suitable for piping assemblies that require reliable sealing, corrosion resistance and the passage of media.

 

Instructions for use

Selection: Choose the appropriate size according to the thread specification of the mounting hole and the inner diameter of the hose or fitting to be connected, and check that the external thread, through hole and step sections are intact and clear.

Cleaning: Clean the connection parts and the through hole before installation to remove oil and dirt. For enhanced sealing, wrap PTFE tape around the external thread or apply a suitable sealant.

Connection: Screw the threaded end smoothly into the mounting hole and tighten to the specified torque. On the other side, slide the hose or fitting onto the multi-step end to the proper position, using a clamp when necessary to ensure a firm connection.

Inspection: After installation, confirm both ends are fully engaged and sealed reliably; in vibrating or high-pressure applications, inspect and re-tighten periodically.

 

Maintenance

Cleaning: Clean oil and dirt from the through hole and external threads regularly to prevent blockage that may affect the passage of media.

Wear inspection: Check the external thread and the multi-step sections for wear or corrosion regularly and replace any abnormal parts in time.

Tightness inspection: For connections under long-term load or vibration, check for loosening regularly and re-tighten in time.

Proper use: Always use matching specifications, avoid overpressure and overload, and never reuse parts with damaged or deformed threads.

 

FAQ

Q: What material is this connector made of?

A: It is made of high-quality stainless steel with excellent rust and corrosion resistance. The specific material grade is subject to the product specification.

 

Q: What is the function of the external thread?

A: The external thread meshes firmly with standard threaded holes for a reliable connection, and sealing can be further enhanced with PTFE tape or sealant applied to the threads.

 

Q: What is the function of the through hole?

A: The through hole allows liquid or gas media to pass through, enabling the connector to combine threaded connection with media transfer in one component.

 

Q: How is the multi-step end used?

A: The multi-step end fits hoses or fittings of different inner diameters; the multiple steps enlarge the contact area for a more secure connection, and a clamp can be used when necessary.

 

Q: How to prevent leakage and loosening?

A: Tighten to the specified torque with proper thread sealing during installation, and inspect and re-tighten periodically. Strengthen sealing and fixing measures under high-pressure or vibrating conditions.
